An online based publication from Security Camera King by Michael Gallardo. This is our series of articles that bring you the interesting developments of technology and the science behind it. All the while reminiscing on nostalgic events, the indulgent in humor, and breaking free of the norm of topics. I hope everyone enjoys
Crime has become increasingly more digital. It is done with ease, almost unnoticeable, hard to trace and able to be done from anywhere. Pre-date main stream technology, if someone robbed a bank, all we had to do was simply turn our heads and look at those who were in the vicinity of the bank being robbed. Now that it can be done digitally, when someone robs a bank, it can be anyone on the face of the earth that has a computer and an internet connection. The thought of this is very disturbing.
Surveillance cameras have been in use for decades to deter crime and to capture video evidence to be used in the prosecution of crimes. However, criminals are aware of surveillance cameras and continually attempt to circumvent them, by various means. Taking advantage of human behavior is one way criminals avoid being filmed in a criminal act. Security guards and even homeowners cannot be everywhere at once. Therefore, many surveillance systems are unattended, in other words, the cameras videotape without the benefit of human analysis. The crimes and actions of others are being recorded and preserved, but the acts in some cases are only detected after the fact. However, new technology has once again caught up with the demand. New technology shows us how to benefit from an auto-tracking PTZ. PTZ is an acronym used to describe cameras that can pan, tilt and zoom.
If you are looking for a digital video security camera that can give you a nice tight video shot, you should consider a varifocal bullet camera. These cameras are economically priced and still provide high definition video images. Unless you specifically buy a “vandal proof” bullet camera, these should be installed where the risk of vandalism is fairly low because the nature of this camera makes it somewhat vulnerable.
Fake security cameras make great tools that can be used to fill in “gaps” between real digital video cameras in a digital video security system. Used as a standalone item, fake security cameras can also be a less expensive alternative to the real thing. Security Camera King carries professional-looking fake security cameras that can help you complete a camera array in a real system or simulate a real system without the full expense.
People who aren’t otherwise familiar with infrared technology might not have any idea what an outdoor IR illuminator is good for. It helps to have a good working knowledge of why infrared surveillance devices work they way they do. People who aren’t as knowledgeable about this area of surveillance might make a few mistakes when purchasing an outdoor IR illuminator device.
Today video surveillance systems are as technologically advanced as the computer and are priced competitively as a security alarm system. Since most digital video security systems are computer compatible it makes sense that more and more people are using them, instead of simple burglar alarms.
What’s the difference, CMOS vs CCD? In the digital video security camera industry there are two types of sensors used to convert light images into (ultimately) electronic images. Those two sensors are the Complementary Metal Oxide Semiconductor or CMOS and the Charged Coupled Device or CCD. In the following article, we’ll take a closer look at each and see how they are both similar and different.
There are several different types of CCTV (Closed Circuit TeleVision) power supplies. Currently in the digital video security industry there are two basic types of power that are used; 1.) 24 Vac and 2.) 12 v DC. Most digital video cameras utilize a low-voltage power supply so there are not as many potentially dangerous factors to be concerned about as there is if they used full household Alternating Current (AC).
Voice activated recorders are exactly what their name implies; they are audio recorders that record when activated by a sound. Voice activated recorders may be used for a multitude of tasks such as securing witness statements, oral note taking, recording college lectures, etc.
